s` claims. (o1. 22o-1o) This invention relates to double walledcontainers and more particularly to double Walled beer barrels made fromsheet metal stampings and provided with a removable or permanent linermade of a material suitable as a container for beer.

By constructing such a barrel with double walls, a number of advantagesare gained thereby. A sturdy construction of sufiicient rigidity towithstand the hard usage to which these barrels are ordinarily subjectedcan be formed of relatively thin sheet material by' stamping methods,portions of the total structure being made in sections which aresubsequently secured together, and yet the total weight can be keptwithin satisfactory limits. To accompany the advantage of using sheetmetal suitable for stamping, provision is made for the lining of theinner shell so that the metal itself need not be one that is especiallyadapted because of its inertness for the reception of beer or otheredible Products.

A double walled construction is readily adapted for the provisions of anopening into the interior shell, larger than the usual filling openingor tap rod opening such as are usually provided in wooden barrels, forexample. Such an enlarged opening can be used to facilitate'the cleaningand the inspection of the barrel, and may also be used for the insertionand removal of a separate removable liner, such as is describedhereinafter.

Another advantage which resides in the double wall construction is thatthe space between the inner and outer shells may be employed for thecirculation of a cooling fluid such as water.

Accordingly, one of the objects of this invention is to provide animproved double walled container and improvements in the manufacturethereof.

Another object of the invention is to provide a double walled containerso designed and constructed as to be appropriately fabricated from thinsheet metal stampings which may be readily assembled into the nishedproduct.

Another object of the invention is to provide improvements in themanufacture of double walled containers provided with unusually largeopenings to facilitate the cleaning of their interiors.

Another object of the invention is to provide an improved form of doublewalled container with a removable flexible'liner and means facilitatingits insertion and removal.

Another object of the invention is to provide an 2 improved form ofdouble walled container which may be made of sheet metal stampings andprovided with lining material which will render the container suitablefor the reception of beverages,

or other edible products.

Another object of the invention is to provide a double walled containerso constructed as to facilitate the circulation of a coolant between theinner and outer shells of the container.

Other objects and advantages or the invention will be alluded tospecifically hereinafter or will become apparent from a perusal of thespecification. v

In the drawings, which illustrate a preferred form of the invention,

Figure 1 is a vertical central section through a container made inaccordance with the present invention;

Figure 2 is a top plan view on an enlarged scale showing the bung end ofthe barrel;

Figure 3 is a sectional view on the line III-III of Figure 2;

Figure 4 is a central vertical section of the top portion of the barrelshowing the bung opening assembly in an exploded view; and

Figure 5 is a sectional view on the line V-V of Figure 4.

Referring further to the drawings, the barrel generally consists ofinner and outer shells, the outer shell being formed from two sheetmetal stampings II and I2 constituting the upper and lower halves of thecompleted outer shell. The

upper half is provided with an annular chime I3 while the lower half isprovided with an annular chime I4. The bottom wall I5 is recessedinwardly considerably from the plane of the outer surface of the chime.The top wall I 6 of the outer shellis provided with a large centralopening in which is xed a removable assembly which carries both a bungopening of standard size and an enlarged opening whose purpose willlater be described.

The inner shell is likewise formed of two sheet metal stampings whichare afterwards united to form a single inner shell. It may be pointedout here that due to the use of lining material for the protection ofthe beer it is not necessary to use for these stampings a metal whichwithout other treatment is suited for a beer container. Accordingly amild steel well adapted to the forming of the stamping of the charactershown may be used.

The inner shell, formed of an upper stamping Il and a. lower stampingI8, is designed to be united securely to the outer shell by means ofangeo Il and 2| formed on the upper and lower halves respectively of theinner shell, these flanges being united to each other by welding. priorto placing the inner shell inside of the outer shell. At the time theinner and outer shells are lplaced together the perimeters oi' theflanges are brought into abutment with the opposing edges of sections Iland l2 of the outer shell after which the flames and the two outer shelledges are all welded together in one operation. Thus the ilanes furnisha means for uniting the inner and outer shells at their equators andalso serve as a spacer between them.

The bottom end oi the inner shell is also dished downwardly as at 2|opposite the bung opening to provide a ilat area of considerable extentwhich may be securely welded to the bottom wall II of the outer shell.Thus the bottom half of the inner shell is ilrmly united to and bracedupon the outer shell, but otherwise is generally spaced apart therefrom.

Provision for uniting the top half of the inner shell to the top half ofthe outer shell is as follows. Before assembling the inner and outershells, a

steel ring 22 is welded to the under side of the top wall il, as is bestillustrated in Figure 3. The upper half of the inner shell is formedwith an upwardly'extending neck 2l which is, during the assembly of theinner and outer shells, welded securely to the ring 22 and the top wallI6, thus providing a firm union between the inner and outer shells atthis plane and also providing a leakproof connection between them atthat position. To add further strength to the outer shell a series ofannular corrugations such as 24 may be provided in the upper and lowerhalves of that shell.

The top wall I6 is also preferably provided with a bushing 25 which maybe welded in place as indicated and provided with a threaded plug 26 forsealing the same. Also the lower half of the outer shell in the vicinityof the bottom chime may be provided with a bushing 21 and a threadedplug 2l.

It should be noted that the flanges I9 and 20 are provided withelongated slots 28 in register with each other, as many of these slotsbeing provided as is necessary to facilitate the circulation of acoolant between the inner and outer shells supplied through one of thebushings 25 or 21 and exhausted through the other, or perhaps merelycontained between and sealed between the inner and outer shells. Evenwhen no coolant is being employed, if the plugs 2B and 28 be in place adeadl air space of considerable insulation value is provided between theinner and outer shells.

Due to the fact that standardized equipment of various types is alreadyin wide use throughout the beer manufacturing and dispensing industries,this barrel is designed to accommodate such equipment. For example, theopening 3| which I have provided in this barrel is intended to'accommodate standard tap pipes. However. equipmentl for filling beerbarrels requires an opening of a larger diameter. corresponding to thediameter of the usual bung openings and lsuch an opening l2 is provided.Furthermore, as I prefer to use a removable flexible liner, theinsertion and removal of that liner is facilitated by providing a stilllarger opening in the top of the barrel, and accordingly such an openingis provided within the neck 23 of the inner shell.

Ifhe removable liner maybe fabricated from various materials which areinert to the action -overlie a washer il. The liner is then clampedagainst the washer by means of a plurality of cap screws Il extendingthrough the fixture 3l which may be a metal forging, casting orstamping, or is otherwise formed from metal or even from non-metallicmaterial. Threaded apertures having been provided in the ring 22 toreceive the threads oi the bolt, the neck of the liner is thus broughtdown into sealed relation with the top wall of the drum and the undersurface of the fixture 31. The washer 25 is provided with a plurality ofgrooves Il constituting air passages extending radially outwardly fromits inner to its outward edges, spaced apart at frequent intervalsaround its circumference, for the purpose of permitting the escape ofair which might become trapped between the liner and the inner shellwhen the liner is being distended.

'I'he fixture 31 and upwardly extending collar Il provide the bung sizeopening 32. The top edge of this collar is provided with a peripheralflange 40 notched out at intervals to permit a cap member 4I having acooperating interrupted flange 42 to be dropped down over the iianges ofthis collar through the interruptions in the flange 4l and thereafterrotated into a tight wedged position. It will be understood that thecooperating interrupted flanges on the cap and collar, as is customaryin such assemblies, have tapered contacting surfaces so that rotation inone direction will wedge the cap downwardly upon the collar whilerotation in the opposite direction will loosen it and permit itsremoval. A compressible gasket 43 will be provided between the collarand cap to seal the ioint.

In Figure 3, I have indicated a liner 44 which will preferably be ofsprayed material in the nature of a coating inert to the action of beerwhich may be applied to the indicated surfaces oi this cap. Likewise asimilar coating 45 may be applied as shown to the fixture 31.

The smallest size opening Il in the cap member 4I will be the sizeusually provided for the tap pipe used in the dispensing of beer, andduring transportation and storage of this barrel may be closed with aplug of wood or some other suitable material. An interrupted ilange 46,best shown in Figures 2 and 3, should be provided on the cap 2| adjacentthe opening 3 to facilitate the attachment of tap pipes or otherfixtures which must be united thereto in sealed relation.

In Figure 4, which shows the fixture I1, cap 4l and other associatedparts in an exploded view preliminary to assembly, the removable liner33 is also shown in the act of being assembled into the barrel.. thedotted portions thereof indicating that it is compacted to a sizepermitting it to be inserted through the opening in the top of the drum,after which it may be expanded in any appropriate manner to lie snuglyagainst the inner shell.

It will now be perceived that I have provided a new type of beer barreland a method of forming the same including the inner and outer shellswhich can be drawn in four separate sections and thereafter united bywelding in a simple and etiicient manner. While a removable liner suchas 33 is preferred, yet I may also provide a sprayed coating for theinside surface of the inner shell, selecting some coating material whichis inert to the beer and having other characteristics suitable forlapplication to and adhesion to the inner steel shell.

While the foregoing description and accompanying drawings illustrate apreferred manner of constructing the barrel in accordance with thepresent invention it should be understood that the invention comprehendsvariations and modifications differing from the enclosed embodiment,Without departing from the scope of the invention defined in theappended claims.
